KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged cutting disc. Pinching or
snagging causes rapid stalling of the rotating wheel which in turn causes the
uncontrolled power tool to be forced in the opposite direction of the wheels rotation.
1.
Maintain a firm grip on the power tool and position your body and arm to allow you to
resist kickback forces. Always use auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up. The operator can control torque reactions or
kickback forces, if proper precautions are taken. Never place your hand near the cutting
disc. The wall chaser may kickback over your hand.
2.
Do not position your body in the area where the power tool will move if kickback occurs.
Kickback will propel the tool in the direction opposite to the wheel's movement at the
point of snagging.
3.
Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
4.
Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create
frequent kickback and loss of control over the power tool.
5.
Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to
twisting or binding of the wheel in the cut and the possibility of kickback or wheel
breakage.
6.
When wheel is binding or when interrupting a cut for any reason, switch off the power tool
and hold the power tool motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the cut while the wheel is in motion, otherwise
kickback may occur. Investigate and take corrective action to eliminate the cause of
wheel binding.
7.
Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is
restarted in the workpiece.
8.
Use extra caution when making a "pocket cut" into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause
kickback.
